REFINE ENERGY COMPLETES WORKOVER PROGRAM
1 February 2019
Refine Energy is pleased to announce that it has successfully completed a 2 well workover program for RCMA Australia Pty Ltd at the Jingemia Production facility asset, south of Dongara, West Australia.
RCMA is the Operator and holds a 93.7% interest in production licence L14 situated in the northern Perth Basin, 360km north of Perth. The permit covers an area of 9,835 acres. RCMA is the operator of the Jingemia field producing light oil from an excellent quality Dongara Sandstone reservoir. Production commenced late 2003 and to date 4.6 million barrels have been produced of the 12 million barrels in place. There are extensive surface facilities in place including oil storage, separators, piping, export and water injection facilities. The field has 4 oil wells producing at 330 bopd and 3 operational and 1 suspended water injection wells.
The well workover program was instigated by RCMA to boost oil production at the facility and address a number of well integrity issues. Since taking over asset operatorship for the L14 Joint Venture, RCMA has commenced a program of compliance, production enhancements and cost reductions that has seen the overall performance of the asset improve, markedly. The workover of the two suspended production wells, J10 and J12 within the Jingemia field, was the next step in driving the production upwards. Both wells are oil producers and have a 7” production casing, 3.5” tubing, are fitted with jet pumps and an approx completion depth of 2.3km. This workover proved challenging as neither well had been in service for a number of years and both had a range of downhole issues.
Refine Energy provided a successful bid for the workover program and the contract was awarded in late November 2018. The scope of work was to manage the well intervention work which included developing the workover programs, updating safety management systems, gaining all necessary environmental, safety and other approvals required under WA regulation, removal of existing tubular and installation of new completion strings/tubular, reconfiguration and installation of jet pumps in BHA and procurement and delivery all materials and supporting services
The workover contract commenced in late November 2018 and completed successfully and to plan mid January 2019. Both wells have been brought back into production and have exceeded forecast expectations.
Speaking of behalf of RCMA, Oil and Gas Director, Chris Newport said, “RCMA view the J10 and J12 workover as a success and would like to thank Refine Energy for delivering this outcome. This program was difficult due to the pre-existing condition of both wells, nonetheless, Refine Energy responded professionally and quickly over the Christmas period to deliver the program as planned.”
This project marks the start of a new business stream for Refine Energy, expanding the capability of the Group into well intervention and workovers. Refine Energy’s CEO, Adam Stepanoff, said recently, “We are extremely pleased to have successfully completed the RCMA workover program. The program presented a number of challenges, both technically and logistically which we managed to overcome. It is also pleasing to see RCMA gain the production benefits. Our workover capability now forms a core part of our business. We can now offer cost competitive well intervention services to the Oil and gas sector in Australia and we will be actively seeking to expand this business on the both the west and east coasts of Australia”
